[SOLVED] TSC on Atom CPU and downscaling CPU frequency

[frednork]

Many Thanks!

working now  

Cool. With this kernel and the NF9C hardware. Make sure to use cpuset in tandem and isolate all the playing software into just a single kernel. The drift across clocks is pretty bug and I'm think it's a hardware or BIOS configuration issue. Isolating every music software into 1 CPU should alleviate that.

Let me know how it sounds.  

Hi I have been using Roonbridge and not sure this gets isolated to cpu1.
Finally had a good listen to the 300hz kernel with both tsc and hpet clock and found I preferred the standard kernel in the end. I also compared it with an SOTM SMS200 ultra and really couldnt pick much between them so congrats on a great bit of software.
I also found that reducing vm stat polling "sysctl -w vm.stat_interval=3600" and to a lesser extent setting the hpet timer frequency " echo "8192" | sudo tee --append /proc/sys/dev/hpet/max-user-freq" helped. These were not my ideas but from @rmpfyf on SNA. 

I also tried to lower cpu frequency but the kernel did not allow it, is this something you have tried previously?
